Money flows out of my spouse’s TFSA and into my unregistered account in 2023 and 2024. Would this not give up a tax advantage?

The money doesn’t “flow" from you spouse’s TFSA to your account.

For each spouse, the TIME MACHINE calculates a surplus or deficit at the end of each year after all incomes, expenses, automatic deposits/withdrawals and taxes have been paid.

Any surplus is dealt with by making deposits to the person's accounts following the Deposit Priorities table applicable at the time.

Any deficit is dealt with by making withdrawals from the person's accounts following the Withdrawal Priorities table applicable at the time.

Remember that for each Deposit or Withdrawal PRIORTIES table there are 2 intermingled: one for each spouse. Joint accounts will be in both spouse's tables. If you have a CCPC with multiple accounts/loans there is a thid table in there too.

You have set your spouse’s expenses to 100K with income of 50K, and your expenses of 60K with income of 105K

Your spouse’s expenses are too high for their income, and thus requires a withdrawal from their accounts. Their first priority for withdrawal is their TFSA.

Your expenses are lower than your income, and thus require a deposit to your accounts. your first priority for deposit is your TFSA if you have room, then your non-registered account.

You may want to adjust the expenses to shift some to you, or make some joint. You could also make your non-registered account joint so that your spouse has access to those funds.

The TIME MACHINE considers account ownership to not run into CRA attribution rules. It won’t just take from your account to pay for your spouse’s expenses/savings, unless your spouse is broke (no savings), then it has no choice.
